Scalable web sessions were a significant improvement brought by 4D v18 R6. They allow you to use 4D tags, 4D actions, and REST API in preemptive processes, even in interpreted mode, on a 4D server. However, to debug such programs, you needed to open your development environment on the server to make it switch to cooperative mode, as the debugger window cannot be opened with preemptive processes. This way, until v19 R2, you could debug REST, 4D actions, or 4D tags. From v19 R3, all of this has become much easier, and you can debug on the server-side simply by attaching the debugger to it, as usual.
In the 4D v18 R6, 4D introduced OAuth 2.0 authentication to access emails through IMAP, SMTP, or POP3 transporters. Starting with 4D v19 R3, 4D continues to implement OAuth 2.0 protocol and provides a way to request easily by programming a token from the Microsoft identity platform to connect to the API for Microsoft 365.
With COVID-19, the remote office has become a new standard, and video conferencing is becoming commonplace for professionals. As a result, more and more professionals have started weaving video conferencing features into their applications. To allow you to display video conferencing from different sources like Zoom, Microsoft Teams, and others, we now support audio and video streams in web areas!
Many of you have already taken the leap and started using ORDA. To ease your coding experience, we are glad to announce that Blobs are now fully supported in ORDA, like any other type. After the first step in 4D v19 R2, with the support of the Blobs in objects, 4D v19 R3 brings the support of Blobs in ORDA.
4D v19 R2 comes with a new version of SpreadJS and a Ribbon update that is compatible with it. Let’s discover the new features offered by this new version.
When printing, page break location is set by default, but you can adjust the print area by defining your own page breaks.
Starting with 4D v19 R2, to help your customers choose where they want to place their page breaks, 4D View Pro lets you add and remove page breaks manually, and also display the print preview lines.
Sometimes, you need to display different tables of information in one document. For better visibility, it’s often necessary to display them in different sheets. In this case, you need to create, rename, hide or remove a sheet, or simply know which sheet the user is currently on.
With 4D v19 R2, you can manage the sheets in your 4D View Pro documents by programming.
With the introduction of classes in the 4D environment, the need to store your data in objects, and especially blobs, has increased. That’s why 4D v19 R2 lets you encapsulate blobs in objects.
Beyond the storage aspect, since the blob object is a reference type, your performance in terms of memory occupation and speed will be greatly improved.
Delimited files such as “.csv” or “.txt” are commonly used formats for importing or exporting data. Because delimited files can be generated and manipulated easily, more and more data published on the Web is tabular data, usually published as comma-separated values.
A good way to format this data and show it to your customers is to use 4D View Pro.
4D v19 comes with a new a new version of SpreadJS and a new version of the ribbon. Besides the fresh look, we have added new features to support the new functionalities of SpreadJS v14.
